The latter calls can be partitioned to groups (combined fragment) to show according to which condition each group will execute. opt: creates a single branch Here is a sequence diagram template that shows how opt and alt fragments can be used in an interaction. the fragment can have only one thread executing it at once. If you do not hold down the Alt key the selected Message will move close to the next Message but will not go past it. One approach is to use multiple sequence diagrams—one that shows the polymorphic message to the abstract superclass or interface object, and then separate sequence diagrams detailing each polymorphic case, each starting with … Method logic: Just as you might use a UML sequence diagram to explore the logic of a use case, you can use it to explore the logic of any function, procedure, or complex process.

Click the example sequence diagram images to append them to the diagram, hover to see the example script. if (condition1) then Let's start with the happy flow. Indeed, the activity diagram is more appropriate to model control logic that involves conditions, loop etc, but in practice, most developers prefer to stick with the sequence diagram to show how objects interact together with the control logic involved. Lower equals Later). Note that this is only true for sequence diagrams, rules are different … Sequence diagrams describe interactions among classes in terms of an exchange of messages over time. Divides fragment into groups and defines condition for each group -  only the one whose condition is true will execute . They capture the interaction between objects in the context of a collaboration. Since our class diagram is actually the diagram of our backend API, the user interface here is not a class.
